OCD-EIC1B-0013-S100-PRM Profinet MRP and Synchro Shaft

OCD-EIC1B-0013-S100-PRM can be supported by EncoderWorks with a custom compatible replacement focused on Profinet MRP continuity, 13-bit position mapping, and ø10 mm synchro-flange shaft alignment. This model should not be treated as a simple singleturn network encoder. The field risk is that the encoder appears online, but the PLC does not receive the same Profinet profile behavior, preset value, device name, IP strategy, or velocity data as the original device.

The OCD-EIC1B-0013-S100-PRM is a POSITAL IXARC singleturn absolute encoder with Profinet interface, RT/IRT support, optical sensing, 13-bit singleturn resolution, binary code, steel housing, ø58 mm synchro flange, ø10 mm solid shaft, radial M12 Ethernet and power connectors, and IP65 protection.

The first failure boundary is Profinet parameter agreement. This encoder supports profile-based communication, velocity filtering, preset, counting direction, IP address, fractional scaling, and parameter control through GSDML or non-volatile memory. If these settings are not copied, the device may communicate while the controller reads the wrong position or velocity value.

This replacement fails when the Profinet device is visible, but the axis reports the wrong position because preset, fractional scaling, counting direction, IP address, or profile configuration does not match the original encoder. That is a network-parameter failure, not a sensing failure.

The second boundary is Ethernet connector mapping. The encoder uses D-coded M12 Ethernet connectors and an A-coded M12 power connector. Tx/Rx pairs, power supply, GND, shield, device name, and MRP/MRPD ring logic must be checked before startup. A connector may fit mechanically while the network path or redundancy behavior is still wrong.

Mechanically, the ø10 mm solid synchro-flange shaft requires correct coupling alignment. Axial and radial shaft-load values should be treated as limits, not installation preload. Coupling eccentricity, flange misalignment, or cable strain at the radial connectors can create unstable feedback that looks like Profinet noise.

The replacement decision should first confirm Profinet profile compatibility, GSDML project data, IP address or device-name strategy, MRP/MRPD topology, M12 Tx/Rx mapping, 10–32 VDC supply, 13-bit resolution, preset value, counting direction, velocity settings, ø10 mm shaft fit, synchro-flange centering, coupling load, and shield grounding. EncoderWorks treats OCD-EIC1B-0013-S100-PRM as an industrial encoder custom compatible solution where Profinet parameter agreement and synchro-shaft mechanics decide field reliability.

Typical production lead time: 15 working days.
